Genetic evidence for inhibition of bacterial division protein FtsZ by berberine. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Berberine is a plant alkaloid that is widely used as an anti-infective in traditional medicine. Escherichia coli exposed to berberine form filaments, suggesting an antibacterial mechanism that involves inhibition of cell division.

Time-Series Chlorophyll Fluorescence Imaging Reveals Dynamic Photosynthetic Fingerprints of sos Mutants to Drought Stress

open access: yesSensors, 2019
Resistance to drought stress is one of the most favorable traits in breeding programs yet drought stress is one of the most poorly addressed biological processes for both phenomics and genetics.

Signal Enhancement by a Multi-layered Substrate for Mutagen Detection Using an SOS Response-induced Green Fluorescent Protein in Genetically Modified Escherichia coli

open access: yesAnalytical Sciences, 2011
In this paper, we describe a method to enhance the fluorescence signal of mutagen detection using SOS response-induced green fluorescence protein (GFP) in genetically modified Escherichia coli using a multi-layered substrate. To generate E. coli that express SOS response-induced GFP, we constructed a plasmid carrying the RecA promoter located upstream

The repressor PrtR1 and the global H-NS-like regulators MvaT and MvaV enable the fine-tuning of R-tailocin expression in Pseudomonas protegens

open access: yesBMC Microbiology
Background Bacteria rely on an arsenal of weapons to challenge their opponents in highly competitive environments. To specifically counter closely related bacteria, specialized weapons with a narrow activity spectrum are deployed, particularly ...

On the Analysis of Protein Genetic Architecture: Response to “Protein sequence landscapes are not so simple”

open access: yes
ABSTRACT We recently reanalyzed 20 combinatorial mutagenesis datasets using a novel reference-free analysis (RFA) method and showed that high-order epistasis contributes negligibly to protein sequence-function relationships in every case. Dupic, Phillips, and Desai (DPD) commented on a preprint of our work.
